Description

[Detailed description of the invention] [Field of industrial application] This invention relates to an elevating type bathing device that allows a physically disabled person to be placed on a stretcher, moved onto the bathtub, and then raised to take a bath. .

[Prior Art] Conventional elevating type bathing devices are equipped with a switch that manually stops the rising of the bathtub in case of an emergency while the bathtub is rising. It was not equipped with a means to stop the rising of the bathtub.

[Problems to be solved by the invention] In the conventional device as described above, when a bather is placed on a stretcher and moved onto the bathtub, when the stretcher is not moved to the correct position, for example, the stretcher is placed on the edge of the bathtub. While on top of the bathtub, the patient accidentally raised the bathtub, causing it to collide with the stretcher. As a result, the stretcher and the edges of the bathtub were damaged, causing needless fear to the bathers, and sometimes creating a very dangerous situation.

This invention was made to solve this problem, and aims to provide an elevating bathing device that immediately stops rising if an object comes into contact with the edge of the rising bathtub. .

[Means for solving the problem] The elevating type bathing device according to this invention is provided with a stop switch on or near the upper surface of the rim of the bathtub, and when an object comes into contact with or approaches this stop switch,
The bathtub lift control circuit is controlled to immediately stop the bathtub from rising.

[Function] The elevating bathing device of this invention is provided with a stop switch that is activated when an object touches or approaches the upper surface of the bathtub rim or its vicinity, and the stop switch is configured to control the control circuit of the bathtub elevating device. Since the stop switch is pressed by an object or approaches the bathtub, the stop switch can immediately stop the raising and lowering of the bathtub.

[Example] Fig. 1 is a front view showing an elevating type bathing device which is an embodiment of this invention, Fig. 2 is a side view showing the elevating type bathing device, and Fig. 3 is a bathtub of the elevating type bathing device. 4 is a front view showing the case where the 3rd

4 is a stretcher on which a bather is placed, 4 is a movable stretcher stand, 5 is a stop switch, 5a is a stop switch button, 6 is a pantograph, 7 is a hydraulic cylinder, and 8 is a hydraulic unit. As shown in Figures 1 and 2, the stretcher 3
The bather placed on the bathtub 1 is further placed on a movable stretcher 4 and carried to the center of the bathtub 1, as shown in FIGS. 3 and 4.
As shown in the figure, the bathtub 1 is raised to take a bath. In Fig. 5, 9 is an up switch, 10 is a magnetic switch, 11 is a down switch, and 12 is a down switch.
13 is a return switch, and 13 is an emergency stop switch for manually stopping the lifting and lowering of the bathtub 1 in an emergency.
8 is a hydraulic unit consisting of a drive motor 81, a hydraulic pump 82, a switching valve 83, an oil tank 84, and the like.

As shown in FIG. 5, the up switch 9, the magnetic switch 10, the down switch 11, and the return switch 12 are connected in parallel, and a stop switch 5 and an emergency stop switch 13 are connected in series. The rise switch 9, the fall switch 11, and the emergency stop switch 13 are provided on the operation panel of the bathing device (not shown). When the lift switch 9 is turned on, the power to the drive motor 81 is turned on by the magnetic switch 10, and the drive motor 81 drives the hydraulic pump 82 to supply oil to the hydraulic cylinder 7. Push up to raise the bathtub 1. Furthermore, when the lowering switch 11 is turned on, the return switch 12 is activated and the solenoid of the switching valve 83 is energized to switch the switching valve 83 and form an oil bypass, so that the oil in the hydraulic cylinder 7 is transferred to the oil tank 84. Now it is possible to return, and the pantograph 6 and bathtub 1 descend under their own weight.

The stop switch 5 is attached to the upper edge of the bathtub 1 as shown in FIG. Lifting will stop.

The stop switch 5 is not limited to the one shown in FIG.
When an object makes contact and pressure is applied, the control circuit is turned off.
When the state or object is metal,
Any device that turns off the control circuit when approached, such as a proximity switch, may be used. Also, bathtub 1
In the case of FRP, the proximity switch may be installed close to the back side of the edge of the bathtub 1. In addition, for a switch such as a tape switch that turns on when pressure is applied, the stop switch 5 in the control circuit is replaced with a current breaker, and a tape switch is attached to the top surface of the rim of the bathtub 1. The above current circuit breaker is activated.

[Effects of the device] As explained above, this device has a structure in which a stop switch is provided on the upper surface of the rim of the bathtub to stop the rise of the bathtub in the elevating bathing device, so that the stretcher carrying the bather can be placed in a safe position. Even if the bathtub is accidentally raised before it is transferred to the bathtub, the stop switch will operate and stop the bathtub from rising, preventing damage to the bathtub, stretcher, etc., and posing no danger to bathers. It has excellent effects.
